The Bugatti WR16 is a quad-turbocharged, W16 engine, manufactured under the high-performance luxury sports car marque Bugatti, since 2005.[2][3]
The cylinder block and crankcase is made of a forged aluminum alloy, with the cylinder bores plasma coated,
The crankshaft is an die-forged steel crankshaft, the connecting rods being made of lightweight titanium,

Volkswagen is a shareholder of Bugatti stock and shares in the profits of Bugatti products as of 2024.
In 2021, Bugatti announced the retirement of the W16 engine, making the Bugatti Chiron Super Sport L'Ultime, which ended production in May 2024, the final automobile to use the engine.[4]
The W16 engine that Volkswagen Group uses in its Bugatti Veyron and Chiron has a displacement of 8.0 L (488 cu in) and four turbochargers. It is effectively two narrow-angle VR8 engines (based on the VR6 design) mated at an included angle of 90 degrees on a common crankshaft.[5]
The most powerful version of this engine, installed in the Bugatti Bolide, generates 1,361 kW (1,825 hp; 1,850 PS) at 7,000 rpm, and 1,364 lb⋅ft (1,849 N⋅m).[6][7]
